Website privacy

Your analytics choice

This website loads Google Analytics automatically and uses analytics cookies to understand visits, card views, searches, price comparisons, catalog browsing, sorting, pagination, image enlargement, deliberate chart exploration, sale-listing clicks and clicks to our app, unless you have saved a choice to turn analytics off. Browsing and searching work with analytics turned off. Google receives usage and device/browser information; its network requests also expose your IP address to Google. We disable advertising personalization and Google signals.

Our events omit search text, search query strings and listing titles. We do not send names, email addresses, scanned images or your app collection. Events may include public card identifiers, result counts, page type, button placement and a count of deliberate actions. Google Analytics groups activity into sessions to measure visit depth and return usage. Campaign codes help us understand where visitors come from.

Use Analytics preferences in the footer to turn analytics off or on. Your choice is stored in this browser for up to 180 days. Turning analytics off stops collection and removes this site's Google Analytics cookies; it does not erase data already collected. Clearing browser storage or letting your choice expire restores automatic analytics.

Photo search

Photo search processes your card photo on this device. One photo and its search result are saved in this browser until you cancel or search again; clearing browser storage also removes them. A numerical image representation is sent to KnowMyCards to find possible matches. When the scanner displays the pilot notice, it also automatically saves the accepted card crop, match predictions, processing timings, browser family/version, card links you open and any Correct card text you enter to private KnowMyCards storage for improving recognition. Original photos, private camera metadata, image vectors and device identifiers are not included in these examples. Opening a match is a provisional hint, not a verified label. Server examples expire after 30 days with hourly cleanup; selected examples may be exported privately for development and labeling. A bounded browser upload queue retries while the scanner is open and expires pending examples after seven days when the scanner next runs. Cancel or Scan again clears the current browser search, but does not delete uploaded or queued pilot examples. No pilot images or feedback go to Google Analytics. The recognition service itself does not store your photo or representation, and records request status, processing time and queue size. The photo-search page does not load Google Analytics. Result artwork loads from the listed image providers.

Other website requests

The hosting service processes requests needed to serve pages. Card images load from the image providers shown on the site. External sale and app links take you to services with their own privacy practices. This notice covers the website, not the iPhone app.
